* fix(nix): use --rebuild in fix-lockfiles to bypass cached FOD store paths
fix-lockfiles checked npm lockfile hashes by running
`nix build .#<attr>.npmDeps`, but fetchNpmDeps is a fixed-output
derivation — if the old store path exists locally, Nix returns it from
cache without re-fetching. This caused the script to report "ok" even
when hashes were stale, while CI (with no cache) failed with a hash
mismatch.
Adding --rebuild forces Nix to re-derive and verify the output hash
against the declared one, catching staleness regardless of local cache
state. Also updates the tui and web npm deps hashes that were stale.
* fix(nix): regenerate ui-tui lockfile to add missing @emnapi entries
npm ci was failing because @emnapi/core and @emnapi/runtime were
missing from ui-tui/package-lock.json despite being required as peer
deps by @napi-rs/wasm-runtime (via @rolldown/binding-wasm32-wasi).
Running npm install --package-lock-only adds the missing entries.
The npmDepsHash reverts to its previous value since fetchNpmDeps was
already fetching these packages as transitive dependencies.
